There are about 5,500 Geodetic Survey Control Stations in Hong Kong, including trigonometric stations, bench marks and traverse stations. The coordinates of these stations can be widely adopted for positioning tasks. The Database files (xls/xml files) contains the core information of the stations, and the Control Stations Index (kml/gml files) can be used for visualization in web maps / GIS systems. Coordinates in the Control Stations Index are approximate and should be used for reference only. Please refer to the corresponding Database files for the surveyed coordinates.
